I think this violates U-boot policy of only touching hardware if it's 
used, but Wolfgang can say for sure.  In general, initialize() functions 
should just set up data structures and register the device.  There's a 
long history of MAC-address issues with ARM chips and Linux that I've 
happily stayed clear of so can't claim to be an expert here.

regards,
Ben
